w. L. CHEW MOP WRINGER May 26, 1936.

' Filed June/10, 1935 2 Sheets-Sheet 2 Snow/M4 Patented May 26, 1936 UITED STATES T OFFICE 13 Claims.

The invention relates to a mop wringer.

The object of the present invention is to improve the construction of mop wringers by doing away with operating members, such as hand levers or foot levers, and to provide a simple, practical and efiicient mop wringer of strong, durable and comparatively inexpensive construction adapted to be operated solely by the pressure of a mop introduced into the mop wringer for causing mop squeezing members to compress the mop and squeeze water out of the same.

A further object of the invention is to provide a mop wringer of this character capable, after being operated to squeeze water out of a mop, of opening automatically when relieved of pressure so that the mop may be readily removed from the wringer, and the latter arranged for subsequent use.

With these and other objects in view, the invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings and pointed out in the claims hereto appended, it being understood that various changes in the form, proportions and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings:

Figure 1 is a perspective view of a mop wringer constructed in accordance with this invention.

Figure 2 is a transverse sectional view of the same showing the mop wringer mounted upon a receptacle, the mop squeezing leaves being in their open position.

Figure 3 is a similar view, the mop squeezing leaves being in their closed position.

Figure 4 is a central vertical sectional view taken longitudinally of the mop wringer.

Figure 5 is a detail perspective view of the mop squeezing leaves and the c'fosshead member.

Figure 6 is a detail end view of a portion of the mop wringer illustrating the arrangement of the links.

In the accompanying drawings, in which is illustrated the preferred embodiment of the invention, the mop wringer comprises in its construction a casing or housing I constituting a support for the mop wringing mechanism and composed of an outer imperforate side wall 2 and end walls 3, the housing or casing being open at the top, bottom and inner side. The end walls 3 are preferably provided with a slight downward taper and they are connected at the top and bottom at the opening in the side of the housing by upper and lower horizontal connecting bars 4 and 5. The housing may be constructed of metal and consist of a casting but any suitable material may, of course, be employed in the construction of the housing. The end walls are provided with apertures preferably consisting of curved slits 6 and the partially severed metal is preferably deflected slightly to provide a shield at each aperture to prevent water passing through the apertures from splashing upwardly.

The housing is designed to be mounted on the upper edge of a tub, bucket or analogous receptacle and it is provided at its outer side with recesses l which receive the upper edge of the receptacle 8. The lower connecting bar 5 is provided at its terminals with extended claws 9 adapted to engage the upper edge of the receptacle and in order to firmly maintain the wringer in its position upon the receptacle the housing is provided at the outer side with legs ill extending downwardly and outwardly from the outer side wall 2 and designed to be of a length to rest upon the floor or other surface upon which the receptacle 8 may be placed. The legs ii) are preferably curved as shown and the mop wringer when in use extends inwardly over the receptacle so that water squeezed from a mop will flow into the receptacle.

Within the housing is arranged a pair of substantially rectangular mop squeezing leaves H constructed of suitable metal and arranged in an upright position and provided at their lower edges with aligned eyes l2 through which passes a horizontal pintle 13 of a vertically slidable crosshead member It. The mop squeezing leaves are provided at their upper edges with rods [5 projecting beyond the side edges of the leaves l and arranged in transversely disposed guide slots [6 formed in the end walls 3 of the housing adjacent the upper edges thereof. The guide slots [6 which are preferably horizontal terminate short of the center of the upper portions of the said side walls 3 and the end portions of the rods [5 project through the guide slots I6 and are connected by links I! to the upper ends i8 of vertical rods 1 9 constituting slides for the crosshead member and guided in vertical openings 20 of Webs or flanges 2! of the end Walls of the housing. The upper ends l8 of the rods [9 are bent at right angles and they form pivots for the links I! which extend upwardly and outwardly from the upper ends of the rods I9 to the projecting portions 22 of the rods l5. The links I! are provided at their ends with suitable eyes 23 and 24 to receive the ends I 8 of the rods [9 and the terminals 22 of the rods l5. The eyes 24 are elongated or in the form of slots to permit the necessary play of the pivotal connection between the links and the upper ends of the mop squeezing leaves.

The crosshead member I 41 is composed of an inverted U-shaped mop receiving loop 25 forming an open frame and connected at its ends with the horizontal pintle I3. The inverted U-shaped loop which is located between the mop squeezing leaves is also connected by lower approximately U-shaped portions or bends 26 with the lower ends of the rods 19. The rods l9 are located exteriorly of the end walls 3 and the bends 26 extend beneath the end walls and are formed integral with the inverted U-shaped loop and the horizontal pintle l3. The webs or flanges 2! preferably extend across the lower ends of the side walls 3 and guide the slides I9 in the upward and downward movement of the crosshead member M. The loop portion 25 of the crosshead member 14 is arranged interiorly of the housing and between the leaves II in position to be engaged by the head of a mop which is adapted by downward pressure to move the crosshead member downwardly and thereby move the leaves inwardly to squeeze the mop and express water from the same. The mop engaged loop 25 is of a size to extend to the upper portions of the leaves so that the major portion of the surfaces of the leaves will operate on a mop head for squeezing the same.

After the mop wringer has been operated by a mop to squeeze the water from the mop head, the leaves H are automatically opened when the loop 25 is relieved of pressure in withdrawing the mop from the wringer. This automatic opening of the leaves is effected by springs 21' having coils 28 disposed on the terminal pivot portions I8 of the slides 19. The ends 29 of the springs are bent around or otherwise engaged with the links H for swinging the same outwardly to move the projecting guided portions of the leaves outwardly in the guide slots it. The downward movement of the crosshead member carries the guided portions 22 of the leaves inwardly and the upward movement of the crosshead member and the outward movement of the links I1 move the said guided portions 22 outwardly for opening the mop squeezing leaves.

The lower portions of the mop squeezing leaves are preferably provided with corrugations 30 substantially the same as those of an ordinary washboard and the said leaves are provided at intervals with apertures 3| preferably formed by curved slits which provide shields 32 above the apertures to prevent upward splashing of water passing through the apertures. Also the leaves are provided at their side edges with recesses 33 located adjacent the lower edges of the leaves which enable the leaves to clear the lower ends of the sides of the mop engaged loop 25 so that the latter may occupy a position between the leaves without interfering with substantial closing of the leaves on a mop head.
